How do I use Stimpaks and RadAways on Dwellers in the Wasteland?

So, in Fallout Shelter, whenever I send my Dwellers to the Wasteland, I give them five Stimpaks and five RadAways, but they never use them when they are injured/radiated. I don't know how to make my Dwellers use them. How do I do this?
Best Answer
There is no way to force them to use them, they will just use them on their own until their stock you give them when you send them out goes away.
Nothing (that is in the game right now) can cause them to die in a single attack that they would not be able to heal from so no worries there. When they get up to the radiation amount a RadAway would heal then they will use one, then their health is low enough for a Stimpack to fill it up, they will use it.
A good ratio is 2 to 1 from Stimpacks to Radaway. I generally will send out my guys with 20 Stim Packs and 10 Rad Aways though they will often still return with a RadAway or two on them. I will also do 15 and 10 if I am low. Your residents will never need RadAway unless you run low on water so as long as that is ok do not fear sending more with your guys in the wastes.

Stimpaks can also be issued to dwellers out exploring, allowing them to heal themselves and explore for longer. A dweller going into the wasteland can hold a maximum of 25 stimpaks, and tapping the stimpack icon when sending them will outfit them with that amount.How do you use RadAway and Stimpacks?

Uses. RadAway is used to heal 50% of vault dwellers radiation damage, however it cannot replenish the dwellers health, only remove radiation from them.

Answer 2
As far as I know, you don't. They decide when to use them.
Answer 3
You can't use them. Your person will not die as long as you send radaways and stimpacks with them. Your person will use the power ups when they are low on health/water.
Answer 4
You can use them I'm your traveler comes back without any left. Mine just did and his little speaking bubble said things like "I'm feeling nauseous". And I was able to give him a rad away and a stimpack. He's good now.
